Grissom: There are three things in human life that are important, the first is to be kind, the second one is to be kind and the third one is to be kind.
Sara: Henry James.
Grissom: Very good, author of one of the greatest horror stories ever written, Turn of the Screw, and I'm looking for one.
Sara: A screw?
Grissom: Yes.

Grissom: There's a theory in art that the Mona Lisa was really a feminized version of Leonardo Da Vinci himself.
Sara: Concept suggests ... Deep down we're all narcissists?
Grissom: Yeah. What attracts us the most is ourselves.

Grissom: This is the first time a roller coaster has derailed in Clark County. Huge criminial and civil liabitilities issues, so keep it quiet. Photograph the scene. Bag and tag the detritus. Forklift anything bigger than Greg. We're going to put up a tent on the other side of the parking lot for crime scene reconstruction. Questions?
Greg: Yeah. What's that guy doing so far away from the others?
Grissom: Curious, isn' t it? [walks away]
Greg: So when he asks if anybody has any questions he's not really asking?

Grissom: To get to the evidence, we may destroy the evidence.
Catherine: Do you get these haiku's out of a book, or do they just come to you?
Grissom: Every time you find a body, you have to choose a path. And when you take that path, grasshopper, you risk destroying the evidence.
Catherine: We grab a trough and some fine-mesh screens and pretend like we're panning for gold, Master.

Grissom: Tom Haviland's attorneys are not waiving time.
Nick: Are you serious?
Sara: They're actually exercising their right to a speedy trial?
Gil: No requests for continuances, no stall tactics. They're pushing for their day in court.
Warrick: Good defense attorney always does the last thing you expect.
Catherine: Yeah. What typically drags on for months has now been put on the fast track and the prelim is less than 72 hours.
Greg: I'm only done processing half the evidence.
Catherine: You're going to have to call in help, because if the judge thinks that our evidence isn't strong enough to go to trial, he's going to dismiss the charges on Tom.
Sara: Can't the D.A. drop the charges and we'll refile when we get our evidence together?
Catherine: Sure, but the odds are that Tom will relocate to Europe and pull a Polanski.
Greg: And what's a Polanski?
Grissom: Get-out-of-jail-free card. One more thing: Westcott just added a forensic scientist to their roster. She wants him to examine every piece of evidence we have against Haviland.
Nick: As soon as it's processed they'll get a copy of our report.
Gil: They're entitled to see it as it's processed.
Nick: I've never done a case where the defendant took advantage of that rule of discovery.
Gil: Well, when you can't attack the evidence itself, you attack the method of gathering the evidence.
Sara: So who's their guy?
Grissom: Dr. Phillip Gerard.
Sara: Phillip Gerard? Your mentor is their forensic scientist?
Grissom: Yeah. Marjorie Westcott's a smart lawyer.

Grissom: Two things that have nothing to do with each other.
Sara: Or everything.
(Sara walks out to find Grissom pacing furiously)

Grissom: Until we can explain why there was gasoline in the bedroom closet the charges stand.
Frank: Then I guess I'm a dead man.

Grissom: We both have jobs that begin after the crime.
Father Powell: After the sin.
Grissom: Some people would call that a career in futility.
Father Powell: Some people call it a vocation.

Grissom: We need a treadmill, a big one.
Nick: All right, to do what?
Grissom: To exercise a bus.

Grissom: We told them what happened.
Catherine: Yeah. But we didn't give them what they needed... closure.
Grissom: Truth brings closure.
Catherine: Not always.

Grissom: We're going off the board, tonight.
Sara: Off the board?
Catherine: The ones that got away. [Gestures to the fish shaped bulletin board] Fish.
Sara: Oh. I missed that one.

Grissom: Well, at least we know where he came from. (shines his flashlight down the sewer)
Catherine: Aren't we going to at least draw straws?
Grissom: No.

Grissom: Well, in this case we're going to recreate the flight from ... 1630 hours on. [points to Brass] You are in 4B.
Brass: Lou.
Catherine: Lou -- the angry businessman. How about that?
Brass: [Sarcastic] Ha ha.
Sara: I want to be Shannon.
Grissom: Good.
Warrick: The stewardess.
Sara: Excuse me, it's "Flight Attendant".
Grissom: Catherine, the doctor, 3E.
Catherine: Single mom. What an imagination you have.
Grissom: [points to Nick and Warrick] Max and Marlene, 2E and F. You two are married. Who wants to wear the pants?
Nick: CSI-3 seniority, "sweetie".
Warrick: Yeah, whatever. You're henpecked anyway.
Sara: [To Grissom] Let me guess; you're the computer geek.
Grissom: In the interest of clarity, yes. Nate in 2C.

Grissom: Well, it's always good to know what you don't know.

Grissom: What are you so afraid of, Conrad? We're just a couple of science geeks. Why can't we work together?
Ecklie: No, we are public servants. We investigate cases as efficiently as we can and then we move on. We're not a clearinghouse for defendants on the eve of trial who don't like what we've turned up.
Grissom: Yes, we are.. if it's our mistake that put them there.
Ecklie: Fine. Spin your wheels.
